I use sRGB unless I have a special image with saturated colors. Then, if I am going to print it, I work in aRGB. It's just what I have found works for me.

It's not so much saturated colors, it's that you have more definition or color shades when you start in ProPhotoRGB and send it to the printer than when starting from sRGB.

You actually have courser graduations with a larger color space if the bit depth stays the same. If you are inside the color space, there are no special colors in proRGB that aren't in sRGB, except when you get "outside the box" with the colors. And that image is so hot, many parts of like those yellow trees are simply blown out.

Use the link on the bottom of this page, then print the file as-is (ProPhotoRGB), convert to sRGB and print again. Then compare: http://outbackprint.outbackphoto.com/printinginsights/pi048/essay.html

I downloaded and played with this. Most of the super saturated colors in this file (esp the color patches) are way outside the gamut of my printer too. I have no need or desire to deal with files like that. I know some people like that "velvia look", it's not my style.

Below three times the patches from the file:

  • screen dump of the gamma warning when proofed for the paper
  • a (quick) reproduction of the print made using Pro PhotoRGB
  • an equal reproduction of the print made after conversion to sRGB

You can see that:

  • in the Pro PhotoRGB print the shades are more defined/separated (greens for instaance); the sRGB print tends to make close tones equal
  • The sRGB print actually shows some colors more saturated (strong reds/magentas for instance).

So there's more subtlety to it than one might think based on what Photoshop tells you.
